(54) Vehicle dynamic control system


(57) The present invention provides a vehicle dynamic control system which can carry out smooth and natural vehicle dynamic control even when road data are discontinuous.
The vehicle dynamic control value calculator 4 calculates vehicle dynamic control value based on vehicle running conditions and road data from the road data recognizer 3. The vehicle dynamic control value calculator 4, upon receipt of discord signal and after predetermined calculation cycles passed, reduces gradually vehicle control value to 0 (zero). The calculator 4 increase vehicle dynamic control value gradually to a value corresponding to the road data and the vehicle running conditions in predetermined calculation cycles, when reception of discord signal is discontinued.
When the calculator 4 receives discord signal but predetermined number of calculation cycles is not counted yet, vehicle dynamic control value is calculated based on road data previously detected.
